The Eagle River is a 2.6-mile-long (4.2 km)[2] stream on the Keweenaw Peninsula of the U.S. state of Michigan.

The west branch rises about three miles southwest of Phoenix in northeastern Allouez Township.

Cliff Drive runs alongside the river, and is joined by U.S. Highway 41 and M-26 about a mile and a quarter southeast of Phoenix.

The only significant tributary on the west branch is Brodie Creek, which rises a bit further inland from the Cliff Range and enters the west branch just outside Phoenix.

It flows west along the south side of the Cliff Range, paralleled by US 41.
